Very Good Glossary from the AAPI  :::

Is a general term that describes unusual experiences that lack a scientific explanation, or phenomena alleged to be outside of science's current ability to explain or measure. Parasychology, it is used to describe the potentially psychic phenomena of telepathy, extra-sensory perception, psychokinesis, ghosts, and hauntings.

Is popularly held to be the disembodied spirit or soul of a deceased person. Popularly described as insubstantial and partly transparent, ghosts are reported to haunt particular locations that they were associated with in life or at time of death.

Has many differing meanings and connotations, but commonly refers to a supernatural being or essence — transcendent and therefore metaphysical in its nature.

Is used in a general sense of a being, whether or not the referent has material existence; e.g., is often referred to as an entity with no corporeal form, such as a language. It is also often used to refer to ghosts and other spirits.

Intelligent haunting:
A haunting that is aware of it’s own presence and tries to interact with our known world. An intelligent haunt will usually include an interaction with EVP sessions, KII Meters and showing themselves when asked

Residual haunting:
AKA a restligeist (German loan word) from restlich (residual) and Geist (ghost), is thought by some to be a replayed haunting in which no intelligent ghost, spirit, or other entity is directly involved. Much like a video tape, residual hauntings are playbacks of auditory, visual, olfactory, and other sensory phenomenon which are attributed to a traumatic event, life-altering event, or a common event of a person or place, like an echo of past events.
Alleged residual hauntings often center on moments of intense emotion: someone's beheading, a great battle, a murder, or even a celebration. Paranormal researchers theorize that residual hauntings are the result of discharged personal energy of a person or group of people being imprinted on the surrounding environment, most commonly at or just after death.
One of the first to promulgate the hypothesis of residual haunting was Thomas Charles Lethbridge in books such as Ghost and Ghoul, written in 1961. The subject was explored in Peter Sasdy's 1972 television play The Stone Tape, written by Nigel Kneale. The popularity of the program has led to residual haunting becoming known colloquially as the Stone Tape theory.

Electronic voice phenomena:
Also referred to as EVPs , are sections of noise on the radio or electronic recording that reveal sounds resembling voices speaking words. Paranormal investigators sometimes interpret these noises as the voices of ghosts or spirits. Recording EVP has become a technique of those who attempt to contact the souls of dead loved ones or during ghost hunting activities. According to parapsychologist Konstantin Raudive, who popularized the idea, EVP are typically brief, usually the length of a word or short phrase.

The electromagnetic field:
Is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. Paranormal investigators believe that an entity can also produce and electromagnetic field.

When regarded as spirits, may belong to either of the classes of spirits recognized by primitive animism; that is to say, they may be human, or non-human, separable souls, or discarnate spirits which have never inhabited a body.

Shadow people:
Can also be known as shadow men, shadow folk, or shadow beings who are supernatural shadow-like creatures of both modern folklore and traditional native American beliefs. According to folklore, they appear as dark forms in the peripheries of people's vision and disintegrate, or move between walls, when noticed.
Reports of shadow people occupy a similar position in the popular consciousness to ghost sightings, but differ in that shadow people are not reported as having human features, wearing modern/period clothing, or attempting to communicate. Witnesses also do not report the same feelings of being in the presence of something that 'was once human'. Some individuals have described being menaced, chased, or in some rare instances, attacked by shadow people. There have also been reports of shadow people appearing in front of witnesses and lingering for several seconds before disappearing. Witnesses report that encounters are typically accompanied by a feeling of dread.
